Application filed February 3, 191?. Serial No. 148,494.

0 m 0. 1 cm it may (minor-21 Be it ltnown that l, Tr-rouse Loni), a citizen c the United States. residing at Beverly, in the county of and State of Massechusetts, have I invented certain Improve; ments in Shoo-Soles and Froccsses of Manufacturing Some, of which the following description, in connection with the accompanying drawings. is a specification, like reference characters on the drawings indicating like parts in the several figures.

fhis invention relates to improvements in slicemnlzinp and more particularly to the production of shoe bottoms.

Important objects of this invention are to increase durability of shoe bottoms and to cti'ect economies "in the finisning of shoe bottoms. it has heretofore been the custom to scour off the outer skin from leather sole, after it has been attached to a shoe, to expose the groin. then butt the grain to smooth it. and then frequently to stain. black or paint, and subsequently polish, the surface to produce a pleasing appearance. The presont invention has the advantage that no material is removed from the sole leather but all oi the material is retained and the wearing qunli ies of all of that material are enhanced; and that economies are effected which may include the saving of the entire crz; enseof the securing, boiling, staining or painting and polishing operations and of the materials used in those operations. Other obic is and advantages of this invention will appear as the invention is further explained. I

in one of its important aspects this invenion consists in bottom finishing a leather sole prior to its attachment to the shoe by breaking up its trend surface, by compres sion. into minute raised and depressed are in such close proximity to each other as to transform the original natural surface oppcnrnnce. requiring no scouring; or butting of the sole :iiter tle sole is attached to the shoe, and attaching the bottom finished sole to a shoe. in prnc" this on oi my invention l have "found. it "t "unto cons to subject n sole to a. pressure of :ointen to tons per square inch between pressure plate engaging; the flesh side the sole and an opposed grain side engaging plate or die the working "face of which provided with a narrow plain border surrounding a slightly raised portion that is corrugated by closely adjacent oblique intersecting grooves reaching to the level of the border and producing pyramidal projections. W hen asole is subjected to the described pressure between said plate and die the sole is condensed, the narrow margin rendered hard and smooth, and the area inside o1 said margin has its surface broken up into closely adjacent raised and depressed faces each of small area by the action of said corrugated area of the die, to

transform the unpleasing appearance of the glazed skin of the leather into a finely reticulated pleasing appearance.

To insure the best results, the edges of the sole may be confined during its treatment, whereby spreading of the sole under pressure is prevented or limited and the density of its marginal portion better controlled as well as the size of the finished sole and its edge contour and finish determinedwith precision. The narrow marginal border provides a place in which a line of nails or stitching may be advantageously placed. This treatment produces a completely bottom finished sole requiring no further finishing treatment after its application to the shoe. The great pressure applied to the sole produces a surface density that rcndersthe surfn ce appearance of the sole substantially unnifected by the treatment to which the shoe is subiected in the usual sole leveling" operation.

The improved sole. bottom finished before it is attached; to the shoe, is also 21. port of the invention.

The various aspects and parts of this invention will be more fully understood from the following description and accompanying drawings and will then be particularly pointed out in the claims.

Having described my invention, What-1 claim as new and desire to secure by Letters Patent of the United States is:-

1. That improvement in methods of male ing shoes which consists in bottom finishing a leather sole prior to its attachment to the shoe by breaking up its tread surface, by compression, into minute raised and depressed areas in such close proximity to each other as to transform the original natural surface appearance of the leather into a pleasing surface appearance requiring no scouring 0r buffing of the sole after it is attached to the shoe.
